Given numbers are 430, 670, 342, 658

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(430, 670) = 28810

GCD(430, 670) = ( 430 x 670 ) / 28810

= 430 / 670

= 430

Step2:

LCM(10, 342) = 1710

GCD(10, 342) = ( 10 x 342 ) / 1710

= 10 / 342

= 10

Step3:

LCM(2, 658) = 658

GCD(2, 658) = ( 2 x 658 ) / 658

= 2 / 658

= 2

So, Greatest Common Divisor of 430, 670, 342, 658 is 2
